Class SurfaceTextureWrapper

java.lang.Object

io.flutter.embedding.engine.renderer.SurfaceTextureWrapper

public class SurfaceTextureWrapper
extends Object

A wrapper for a SurfaceTexture that tracks whether the texture has been released.

The engine calls SurfaceTexture.release on the platform thread, but updateTexImage is called on the raster thread. This wrapper will prevent updateTexImage calls on an abandoned texture.

The provided onFrameConsumed callback must be invoked when the most recent image was consumed.

Parameters:

onFrameConsumed - The callback after the updateTexImage is called.
